Can you build an isolated case for that that reproduces the issue?

Hi there,

We are using Castle Windsor for all our projects with great success, in almost all aspects. However, we have one slight issue with it: performance. Sometimes, when we are deserializing a big result from one of our REST services for example, we see this as a noticeable lag in the responsiveness. I did some quick testing and there’s clearly something fishy here. This code:

public void PerformanceTestTransientViewModel()

{

for (int i = 0; i < 25000; i++)

{

//viewModelFactory.CreateViewModel<TransientViewModel>();

container.ResolveType<TransientViewModel>();

}

}

..takes more than *50 seconds* to execute. (container is an extremely simple wrapper on top of Windsor, because we don’t expose Windsor to our applications directly.)

We are using the typed factory facility (ViewModelFactory is generated using this approach), and I suspected the problem was with the typed factory stuff. But, as you see, I tried it with plain container.ResolveType which is in essence windsorContainer.Resolve<TFrom>() being called, and it was equally slow.

Any hints? What we’ve done sometimes is skipped the proxying/interception in these cases, and instantiated the classes automatically (without even registering them in the IoC) which is a lot faster, but I’d rather not have to that on a massive scale.

Many thanks in advance for your ideas! I can show you more about how exactly we are setting up the Windsor Container if you like, but it’s fairly complex (since we have our own application framework running on top of Windsor), so it’s probably best to look at the specific parts that are relevant.

Best regards,

Per
